A device implementing a dynamic local media access control (MAC) address assignment system may include at least one processor that is configured to initiate a link establishment with a network device. The at least one processor may be further configured to determine whether a previously assigned media access control (MAC) address is stored locally. The at least one processor may be further configured to transmit a message to the network device requesting validation of the previously assigned MAC address when stored locally. The at least one processor may be further configured to communicate using the previously assigned MAC address when the validation is received from the network device, otherwise communicating using a dynamically assigned MAC address received from the network device during the link establishment.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The non-transitory computer-readable medium of claim 1, wherein the first multicast address is associated with one or more address distributing devices and the one or more MAC address response packets are received from the one or more address distributing devices.
3. The non-transitory computer-readable medium of claim 1, wherein the dynamically assigned MAC address comprises a locally unique MAC address.
4. The non-transitory computer-readable medium of claim 1, wherein a source address of the MAC address request packet is set to a reserved MAC address that is not assigned to any device.
5. The non-transitory computer-readable medium of claim 1, wherein the first device identifier comprises at least one of an internet protocol (IP) address, a random number, or an extended unique identifier.
6. The non-transitory computer-readable medium of claim 1, wherein the dynamically assigned MAC address is generated from a 24-bit random value and a pre-configured 24-bit value, wherein the 24-bit random value comprises least significant bits of the dynamically assigned MAC address and the pre-configured 24-bit value comprises most significant bits of the dynamically assigned MAC address.
7. The non-transitory computer-readable medium of claim 1, wherein the MAC address request packet is transmitted via an autonegotiation page.
8. The non-transitory computer-readable medium of claim 7, wherein the one or more MAC address response packets are received via one or more other autonegotiation pages.
9. The non-transitory computer-readable medium of claim 8, wherein the autonegotiation page and the one or more other autonegotiation pages each comprises at least one of a base page or a next page.
11. The method of claim 10, wherein the first multicast address is associated with one or more address distributing devices and the one or more MAC address response packets are received from the one or more address distributing devices.
12. The method of claim 10, wherein the dynamically assigned MAC address comprises a locally unique MAC address.
13. The method of claim 10, wherein a source address of the MAC address request packet is set to a reserved MAC address that is not assigned to any device.
14. The method of claim 10, wherein the first device identifier comprises at least one of an internet protocol (IP) address, a random number, or an extended unique identifier.
15. The method of claim 10, wherein the dynamically assigned MAC address is generated from a 24-bit random value and a pre-configured 24-bit value, wherein the 24-bit random value comprises least significant bits of the dynamically assigned MAC address and the pre-configured 24-bit value comprises most significant bits of the dynamically assigned MAC address.
17. The semiconductor device of claim 16, wherein the first multicast address is associated with one or more address distributing devices and the one or more MAC address response packets are received from the one or more address distributing devices.
18. The semiconductor device of claim 16, wherein the dynamically assigned MAC address comprises a locally unique MAC address.
19. The semiconductor device of claim 16, wherein a source address of the MAC address request packet is set to a reserved MAC address that is not assigned to any device.
20. The semiconductor device of claim 16, wherein the first device identifier comprises at least one of an internet protocol (IP) address, a random number, or an extended unique identifier.
